Hi, I need help on this one. I have a D2CKey installed Japanese console that I did region change and updated to 4.1U using waninokok's update. I know that I need to set the jumper for the modchip to U.S., so I removed the solder for Jumper 2. After that, when I turn the machine one...it did read the backup disc on the channel..but I didn't actually boot the disc.

I then downgraded the console back to 3.2U as my weather/news channel wasn't working and it says it need to do a system update before it can work. So I went back to 3.2U thinking I can then insert a Wii Fit disc to do the update. After downgrading, I noticed the backup disc is no longer read. It can read the original Wii Fit disc.

So now I am stuck as the modchip doesn't seem to read the backup anymore. It was working fine all long, and I assume the connection is intact since it did read the backup zelda I had after I modify the jumper. I don't understand how downgrading would stop a hardmod to work though.

Would really appreciate anyone who could help me to get the D2CKey to read backup again.

Just an update about the problem. So, I updated the system to 4.1U now, and the backup disc is recognized on the channel. But when I try to run it, it gives a black screen disc error, eject disc and turn power off message.

Never had this problem before when it was running as a Japanese console with JP1 and JP 2 bridged.
